The effect of a links from a search engine?

[AMA-DataSet]

Hi everyone,
Iv recently been conducting a link analysis on one of my sites, I downloaded the list from web master tools, but iv noticed a number of links coming from a search engine websites.

At a glance there are maybe 10-15 links from these search engine sites each with a slightly different domain name (e.g: 10search.com, 20search.com, 30search.com etc.) but the same design, same logos and similar results.

What effect would these links have? and should I remove them?

Thank you in advance

Yes,

These sort of links may hurt your website, you need to remove or let it place nofollow under the link tag.
My bet is to remove only. It's not going to help, single link is enough from 15 links .

Hi,

First of all you need to find the links on one of those sites and see if the link is set on no-follow (Web master Tools is showing in the list both do follow and no follow links). If those links are no follow then you should forget about those and focus on something else. If the links are do follow and your link profile is not very strong all together then you can/ should deal with those as it can hurt you even if you had nothing to do with those and the easiest way to handle those is just to disavow - no need to waste time in contacting the sites or looking for removal forms and so on.

Hope it helps.
